Monotouch を使用して iPad アプリを開発しています。

これが私のシナリオです：

タブ付きベースアプリケーションを作成しました。例: Home、Admin、Reports....etc Home タブは UIViewController です。

ホームタブ内に3つのセクションが必要です：たとえば、カテゴリ（ナビゲーションコントロール付きのテーブルビュー（カテゴリ内にサブカテゴリがあるためナビゲーションを使用する理由））、カテゴリテーブルの横、選択されたカテゴリのアイテム（その他のテーブルビュー）、右側は選択されたの詳細ビューですアイテム。

これが私がしたことです....

2 つのテーブルビュー コントローラーを動的に作成し、メイン ビュー コントローラーに追加します。

HomeViewController.cs:

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

         RootViewController rvc = new RootViewController("",UITableViewStyle.Grouped);

        // navigation controller will manage the views displayed and provide navigation buttons
        navigationController = new UINavigationController();
        navigationController.PushViewController(rvc, false);
        navigationController.TopViewController.Title ="Category";

        navigationController.View.Frame = new RectangleF (0, 50, (50), (600));



        // Main window to which we add the navigation controller to
         this.View.AddSubview(navigationController.View);

        itemtable.Delegate = new TableViewDelegate (list);
        itemtable.DataSource = new TableViewDataSource (list);

        // Perform any additional setup after loading the view, typically from a nib.
    }

質問：

  • このシナリオを実行するのは正しい方法ですか?
  • 正常に動作しますが、Item ビューを親 View Controller に追加すると、アクセスできなくなります。つまり、アイテム リストは存在しますが、セルにアクセスできず、セルに触れたり、上げたりスクロールしたりすることはできません。

誰でも私を助けることができますか？

ありがとう

あなたが何をしたかったのか完全にはわかりません。最善の推測を行い、2 つのソリューションを含むサンプルを作成しました。タブごとに 1 つのソリューション。1 つ目は、組み込みの分割ビュー コントローラーを使用します。UISplitViewController がアプリケーションのルートでなければならないいくつかの場所を読みました。タブコントロールの子として追加することで、そのルールを破りました。

2 つ目は、分割コントロールのカスタム バージョンを作成します。
